Application filed February 15, 1915. Serial No. 8,317.

To all whom it may concern:

Be it known that I, FREDERICK R. MER- RELL, a citizen of the United States, residing at Galveston, in the county of Galveston and State of Texas, have invented certain new and useful Improvements in Window-Sash Locks, of which the following is a specification.

This invention relates to improvements in window sash locks,.and has for one of its objects to provide a simply constructed device which may be attached to the upper and lower sash and firmly lock the sash in position while, at the same time effectually preventing the surreptitious movement of the sashes, and so constructed that the attachment to the upper sash does not project into the path of the lower sash nor interfere with its operation.

Another object of the invention is to provide a simply constructed device of this character which may be applied without material structural change to sashes of various sizes.

lVith these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described, and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention, Figure 1 is a view of a portion of a window frame and its sashes with the improvement applied; Fig. 2 is an enlarged view of a portion of a sash and the'adjacent portion of the frame; Fig. 3 is a section on the line 33 of Fig. 2; Fig. 4 is a view from the rear of the improved device detached; Fig. 5 is a view from the inner end of the improved device detached; Fig. 6 is a detached perspective view of the holding bolt of the improved device; Fig. 7 is a detached perspective view of the bolt operating arm of the improved device; Fig. 8 is a detached perspective view of the supporting standard of the improved device.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying draw ings by the same reference characters.

The improved device includes a support, preferably of sheet metal, and comprising a base portion 10 and a bolt supporting portion 11, the latter being disposed at right angles to the base portion, as shown, and perforated to permit the bolt to slide therethrough. The base portion 10 is provided with adepressed portion 12, with a slot 13 through the depressed portion. The base" 10 with its bolt supporting portion 11 are designed to be embedded in the face of the sash, the upper sash being indicated conventionally at 14 and the lower sash at 15. One of the members 10'l1 may be attached to each sash, as shown in Fig. 1, and maybe located at any desired point thereon.

Attached by rivets or like fastening de-- vices 16 to the base 10 is astandard 17, and

pivoted at 18 to the standard is an arm or lever 19 extending by its free end through the slot 13, as shown in Fig. 3. By this means, the member 19 is operative from outside the base with no portion of the member 19 projecting beyond the general face of the sash, the depressed portion 12 permitting of this action. By this arrangement, no portion projects beyond the general face of the sash to lnterfere with the passage of the meeting rail of the lower sash when the de-' vice is applied to the upper sash. WVhen ap-- plied to the lower sash, no portions of the device project beyond the general face of the sash to be engaged by surrounding ob jects or to catch upon curtains, shades or the like. 1 I

The holding bolt portion of the improved device comprises an outer cylindrical portion 20 operating through an aperture in the member 11 and reduced at the inner end, as

represented at 21, and the reduced portion slotted as shown at 22. A pivot 28 is connected to the member 19 and extends through the slot 22, the pivot being somewhat smaller than the slot so that cramping does not result from the operation of the parts. A spring 24 is connected between the bolt 20 and the standard 17 and operates to maintain the bolt yieldably in its outer position. By this simple means, it will be obvious that, when force is applied to the pro-- jecting terminal of the member 19, the bolt 20 will be withdrawn and the sash released. Embedded in the sash at suitable intervals are stops 25 having one side inclined, as represented at 26, and secured in place by a screw 27 or other similar fastening device. Any required number of the members 2526 may be employed and located at suitable intervals in the adjacent portion of the frame of the window, the latter being indicated conventionally at 28. Bearing against the member 19 is a spring 29 and connected at its ends, as shown at 30,to the base 10.

The spring 29 is constantly engaged with the member 19 and prevents undue looseness between the parts.

The improved device is simple in construction, can be inexpensively manufacturedv and applied, and may be of any required form to correspond with the sash to which it is attached.

The free end of the member 19 is preferably enlarged laterally to increase the surface with which the thumb oi. the operator engages.

Having thus described the invention, what is claimed as new is:

1. In a device of the class described, a support including a guide and a base and adapted to be embedded in a sash, said base having a sunken portion with a slot therethrough, a standard eXtending from the base, an arm pivoted to the standard and extending through the slot with its terminal constantly within the sunken portion 1 of the base, and a holding bolt operating through the guide and pivoted at one end Uopies of this patent may be obtained for to the arm whereby the bolt is operative by manipulating the portion of the arm which extends through the slot.

2. In a device of the class described, a support including a guide and a base and adapted to be embedded in a sash, said base having a sunken portion with a slot therethrough, a standard extending from the base, an arm pivoted to the standard and eX- tending through the slot with its terminal constantly within the sunken portion of the base, a holding bolt operating through the guide and having a longitudinal slot, a pivot extending from the arm and through the slot of the bolt, and a spring operating to maintain the bolt yieldably in projected position.

In testimony whereof I alliX my signature in presence of two witnesses.

FREDERICK lt- MERRELL.
